SHADE STRUCTURES, GREENHOUSES, AND ACCESSORIES

We specialize in providing a wide variety of items most useful to greenhouse growers–from

complete shade structures, greenhouse packages, frames, coverings, heating/cooling

systems, to replacement items.

Shade Structures – – We distribute Poly-Tex shade structures. They are available in 20’ X

20’ blocks and are 10’ high. They have 2-1/2”-diameter X 12-gauge vertical posts, and the

shade cloth panels are available in shade factors from 30% to 90%.

High Tunnels – Poly-Tex has gable-style and gothic-style high tunnels, 20’, 24’, or 30’ wide.

The structures come with manual roll-up sidewall vents and hardware for framing in the

endwalls. Contact us for pricing.

Commercial Greenhouses Poly-Tex produces free-standing and gutter-connected models

with widths ranging from 14’ up to 30’. Poly-Tex offers Poly-Vent sidewall venting which is an

option to roll-up sides. The Poly-Vent opens from the top down and can be opened partially.

The Wiggle Wire poly fastening system is used to secure poly film or shade cloth.

Backyard Greenhouses Poly-Tex has several inexpensive models for backyard applications

which are available in widths of 6’ and 8’. The lengths start at 6’ and go up to 20’.

Poly Film Locking Systems – The Wiggle Wire poly film fastener system is an economical

and effective approach for securing single- or double-layer poly film. The system consists of a

base extrusion that can be fastened to wood or steel and will form over arches, and wiggle

wire that fits into the base and holds the poly film in place for the sides and gable arches. The

system holds the poly film firmly in place without pinching or weakening the film.
